| 发明名称 | Synthesis method for magnetite and birnessite aggregate-form mixture | ||
| 摘要 | The present invention relates to a magnetite-birnessite mixture, to a synthesis method therefor, and to a water-treatment method using the same. The magnetite-birnessite mixture synthesis method according to the present invention includes: a first synthesis step in which magnetite is synthesized; a second synthesis step in which manganese is made to adsorb onto the surface of the magnetite by supplying manganese while maintaining a basic state in the presence of the magnetite, and then synthesizing birnessite on the surface of the magnetite by supplying an oxidizing agent and sodium, thereby synthesizing a mixture in which magnetite and birnessite are bound together; and a purification step in which the mixture of magnetite and birnessite is purified. | ||
